| 説明 | Paranthropus boisei (Leakey, 1959) - fossil hominid from the Pleistocene of Tanzania. (replica of OH 5 (National Museum of Tanzania, Dar es Salaam, Tanzania) on public display at the Field Museum of Natural History, Chicago, Illinois, USA)Hominids are humans. Fossils of the human family are known back to the Miocene, with many species known from Pliocene and Pleistocene sedimentary rocks. Only one species in Family Hominidae is alive today, in the late Holocene - that's us, Homo sapiens. Hominids originated in Africa - that's where the oldest human fossils occur. Everyone on Earth is African, from an evolutionary point-of-view.Paranthropus humans were the oddest members of Family Hominidae. Three species are known - they are characterized by having a bony sagittal crest at the top of the skull, a concave upper face and projecting jaw, wide and massive cheek bones, large chewing muscles, and relatively large molar teeth. These hominids had significant sexual dimorphism. They were specialized herbivores, feeding principally on grasses, which is a low nutrient-content food source. Some Paranthropus controlled fire. They were apparently tool makers and tool users.Classification: Animalia, Chordata, Vertebrata, Mammalia, Primates, HominidaeStratigraphy: Koobi Fora Formation, Lower Pleistocene, 1.75 MaLocality: Olduvai Gorge, western Arusha Region, northern Tanzania, eastern Africa |
